  CABRIOLET DOOR WITH ADJUSTABLE RAIL AND METHOD

ASSEMBLY CORRESPONDING

  The invention relates to car doors and windows, and in particular the doors and window lifts cabriolet. Cabriolets are known, including the Peugeot 206CC, in which the door does not have a window frame. It is then particularly important in this case to ensure the adjustment of the position of the top of the window in the direction

cross-section of the vehicle.

  The Peugeot 206CC includes a door window lift with adjustable rail in the transverse direction. The window regulator comprises two rails extending vertically inside a front door. These rails have a slider guide groove. A tab is attached to the bottom of the rail. This tab forms approximately an angle of about 90 relative to the rail and thus protrudes in the transverse direction of the vehicle. A screw is welded on this leg. A trigger guard is arranged against a lower sheet metal return of the door or the frame. The return has an access opening to the trigger guard. This bridge has an oblong hole extending in the transverse direction of the vehicle. The screw passes through the oblong hole, and is fixed by a nut on the trigger guard. When mounting on a production line, the nut is put in place and tightened by the underside of the door. This causes for

  the operator a mounting of the nut tedious and not very ergonomic.

  - There is therefore a need for a window regulator solving one or more of these problems. The invention thus has obj and a window regulator comprising a slider guide rail, a substantially vertical screw, each end has a drive head, a flat surface substantially perpendicular to the guide rail and secured to the rail, capable of transversely slide relative to the screw, in which an oblong hole traversed by the screw is provided, an outer panel, a plate, fixed with respect to the panel, having a thread in which the screw is

Committed.

  According to a variant, the panel is a door panel.

  According to another variant, the window regulator is likely to have access to

  each head of the screw at least during assembly of the vehicle.

  The invention also relates to a method of assembling a door

  according to one of the preceding claims, comprising the steps of inserting the

  Threading the screw in the thread of the plate, adjusting the cross position of the rail relative to the screw, tightening the screw through the upper screw head, loosening the screw through of the lower screw head, H: \ DACIYLO \ 15300 \ 18351 doc-31/08 / 01- 10-08- 1/6 retouching adjustment of the transversal position of the rail with respect to the screw, clamping

  of the screw through the lower screw head.

  Other features and advantages of the invention will be apparent in the reading of

  the following description of embodiments of the invention, given by way of example

  and with reference to the accompanying drawings which show: - Figure 1, a cross-sectional view of a door part according to the invention;

  - Figure 2, a longitudinal sectional view of the door of Figure 1.

  The invention proposes to assemble a window lifter rail on a door or on a frame by means of a vertical screw with two heads. The upper head is used to make a first adjustment of the transverse position of the rail. The lower head is

  used to make a retouch adjustment of the rail's transverse position.

  In the following description, the transverse direction corresponds to the normal

  in the middle plane of the door or a side body panel where applicable.

  Figures 1 and 2 show a door 1 comprising a lift rail 2 according to the invention. The window regulator rail 2 has a slider guide 3. The slider 4 slides in this guide, which can be made for example in the form of slot 5. The guide allows the sliding of the cursor on the rise or fall of the cursor 4. The slider 4 is integral with a window 6. The rail has a leg 7, which is

  disposed approximately at right angles to the guide 3.

  The tab 7 has an oblong hole 8, extending in the transverse direction of the door or the frame if necessary. A double-headed screw 9 is inserted into the oblong hole 8. The screw has an upper head 10 and a lower head 11. The thread of the screw is inserted into a thread of a corresponding nut 12. The nut 12 is fixed by welding to a trigger guard 13. The trigger guard is preferably made in the bottom of the door, at the level o must be placed at the bottom end of the rail. The nut is fixed

  on a flat surface or on a plate of the bridge 13.

  The tab 7 may for example be realized in a fold of sheet metal of the guide rail or with a reported and welded portion, if necessary. The upper surface of the tab forms a seat for the upper screw head 10, so that this screw head can apply a compressive force on the tab. The lower surface of the tab forms a scope for coming into contact with a corresponding surface of the

bridge 13.

  The oblong hole 8 makes it possible to slide the guide transversely relative to the screw during an adjustment. Thus, when the screw is held in place without tightening, the tab is free to slide to fix the transverse position of the rail relative to the outer panel. The transverse position of the window can therefore be

modified in this way.

  H: NDACrYLO \ 18300 \ 18351 doc-31108 / 01- 10 08 - 2/6 When a tightening force is applied between the screw 9 and the nut 12, the contacting surfaces, respectively of the bridge and the tab are immobilized by friction. It is also possible to immobilize the surfaces, respectively of the bridge and the leg by means of adequate stops if the friction force between the bridge and the tab is insufficient. The screw is preferably arranged substantially vertical in the door. Thus, access to his two heads is facilitated. The screw have screw heads 10 and 11 suitable for being rotated by a corresponding tool. The top screw head allows for top placement and clamping, which is ergonomic and therefore reduces the set-up and tightening time of the screw. For example, it is possible to use a hexagonal upper head to have a good ability to grip at a distance. Indeed, the screw is arranged generally at the bottom of the door during assembly of the rail on the door and it is desirable to promote its grip. The lower screw head allows clamping or loosening from below. Thus, when auxiliary elements of the door are mounted, such as a window, speakers, a lock or an inner protective panel, although access to the upper screw head is difficult, access to the head screw lower remains easy to make a possible new adjustment of the transverse position of the window, for example in case of shocks. Moreover, it is preferable to use a lower head called "headless". This head can thus pass through the thread of the nut 9. It is preferable to choose a standard drive impression of the type

  split, hexagon or torx, operable with standard tools.

  In the example of Figures 1 and 2, the lower screw head déDouche down from the door. This provides good access for more precise adjustment after mounting of auxiliary door elements. The lower screw head preferably opens into a lower recess of the door. The screw head remains invisible to the user. The plate and the shrinkage are then preferably made in the form of

  trigger guard, for example by folding or stamping a sheet.

  The invention also relates to a method of assembling a door. The thread of the screw is inserted into the thread of the bridge or into the nut, with the lower screw head facing downwards. The transverse position of the screw in the oblong hole is adjusted, for example on a serial door assembly line. The screw is tightened through the upper screw head. Then, loosen the screw through the lower screw head. Adjustment of the adjustment of the transverse position of the screw in the oblong hole is carried out, for example at the end of the door assembly line when the art of the annexed parts of the door are assembled. The screw is then tightened to immobilize the transverse position of the screw in the oblong hole, and consequently the transverse position of the window and rail H: \ DAC [YLO \ 18300 \ 18351 dx- 31/08 / 01- 10: 08 - 3/6 with respect to the outer panel. The transverse position of the screw in the oblong hole has a great influence on the transverse position of the top of the window. This

  tightening is achieved through the lower screw head.

  Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art. Thus, although it has previously described a nut reported and soldered on the bridge, it can also use any other suitable means, such as a fletage made directly in the thickness of the bridge. Furthermore, although the invention has been described mainly in the case of mounting in a door, the invention also applies to the mounting of the window lifter for the seats

  rear in a chassis with no rear doors.
